摘要
以某简支板梁桥为例,利用桥梁专用有限元软件MIDAS/CIVIL建立全桥空间梁格模型,分析了该桥的静力特性、动力特性,得到相应的理论值,并与实测值进行比较,对新建桥梁结构做出性能评估.结果表明:该桥整体刚度较大,承载能力较好,结构具有一定的安全储备.
Using the finite element software ＂MIDAS＂ and taking a simplified plate girder bridge as an example,the whole space grillage is modeled in this paper.The static characteristics and dynamic characteristics are analyzed,and the corresponding theorey is reviewd.The comparison test shows that the overall stiffness and carrying capacity of the bridge are improved particulary in terms of safty tolerance.
